How to plant Trollius

Trollius are hardy and can tolerate winter temperatures down to -20C. This means you can plant them directly outside in pots or borders in spring and they don’t require any frost protection.

— Soak the roots in water for 3-6 hours prior to planting out.

— Plant your bare roots into temporary pots in spring and grow-on in a sheltered spot outdoors to transplant later in the season, or plant directly into cultivated, weed-free borders.

— Plant the roots so that they are fully submerged with the buds or crown just below the surface and any top growth exposed.

— Plant in borders or containers in full sun or partial shade.

— Space the plants 15-20cm apart.

— Water-in after planting and keep hydrated when in growth.
